Method for multispectral acquisition of image stream and associated image acquisition system

The invention relates to a method for multispectral acquisition of an image stream, in which a sequence of individual images of a scene, in particular in the form of a continuous video image data stream, is acquired as an image stream by means of an image sensor of an image acquisition system. In the method according to the invention, at least two different types of individual images are recorded in different correlated wavelength ranges by means of an image sensor, at least one A-type individual image in the sequence being acquired during a temporal A-type acquisition section, and at least one A-type individual image in the sequence being acquired during a temporal A-type acquisition section. And at least one class B individual image in the sequence is acquired during a class B acquisition section in time. Furthermore, the A-class acquisition section and the B-class acquisition section are temporally separated from each other by a corresponding waiting interval, in which the image data is not sensed by means
